Satellite
Protean offers unique, scalable, cost-effective ICT solutions that innovatively combine technical advances in satellite wireless (VSAT, Low-Data Rate and Digital Audio Broadcasting) networking technologies along with ubiquitous global positioning (GPS) technology.
Satellites are unmatched in their ability to
- provide ubiquitous coverage; last mile connectivity
- create instant communications infrastructure
- be independent of existing terrestrial infrastructure
- be highly survivable
- be inherently scalable
In addition to providing design, architecture and engineering solutions in Satellite Networking, Protean also offers specialized Satellite Network Consulting and Training in:
-
Network Options, Planning and Sizing
- Fixed and Mobile Satellite Networks
- Satellite Frequency bands (L, S, C, X, Ku, Ka) and Satellite Availability
- Multiple Access (FDMA, TDMA, DAMA, Spread Spectrum)
- Network planning (Sizing for Converged Voice, Video, Data applications) Satellite Engineering
- Maximization of satellite capacity (MHz)
- Bandwidth versus power trade-off (Power Equivalent Bandwidth)
- Satellite Link Analysis, Clear-sky margins and Network availability analysis
- Effect of rain on attenuation, cross-polarization interference (Terrestrial interference, cross-pol interference, inter-modulation, Inter-symbol interference, Rain-induced effects, Thermal noise)
- Earth Station elements (Antenna, LNA, HPA, up-converter, down-converter)
- Look angles, Sun outage and antenna coverage
- Baseband planning and lifetime cost optimization Design Trade-offs and Optimization
- Carrier planning (Digital Modulation and Coding Choices, Information burst rate, FEC code rate, Allocated bandwidth per carrier, Adjacent channel interference)
- Inter-modulation interference and Back-off operation
- Outbound and Inbound coverage maps
In addition to using VSAT technologies based on GEO satellites, Protean is well versed in adapting and re-purposing low data-rate and satellite radio technologies to address a wide variety of needs such as selectively addressable closed-user groups, emergency alerts, distance-learning, digital libraries etc.
